Scheduling automatic startup (and shutdown) in Ubuntu
I liked the idea of having my Ubuntu machine startup in time for my arrival at the office. Here's how it's done:
1) Enable your RTC in the BIOS, setting your desired wake-up time
2) Use the rtcwake command to tell the machine when to wake up. Two variants of this:
sudo rtcwake -s 54000 -m disk
will wake the PC in 15 hours, after immediately doing a hibernate, or
sudo rtcwake -s 54000 -m no
will do a wake in 15 hours but nothing more. I like this latter way since I can then also schedule a shutdown using a package such as qshutdown
I did toy with nvram-wakeup, which is useful for setting the RTC while you're running Ubuntu.

And if you get the Grub menu after resuming, the fix is here.

5.45 am...
And I hear a faint rendition of 'Head and shoulders, knees and toes'. When Liam says 'Dada, let's get up. Pleeease.', how can I refuse?

A Hardware Week
It's been a busy hardware-oriented week. This is what I've learned.
1. When your Windows PC gets the blue-screen of death (BSOD) that says 'memory_management', your memory really is fried. I was lucky to get the memory I need from the nearest store, and before you know it I'd not only resolved the problem, but got an extra 1Gb of RAM that makes my laptop noticeably faster.
2. If you've got a old PC with an Intel Socket 775 CPU, do consider swapping out the old 1.3Ghz single core processor for a dual-core 2.6Ghz CPU. For a few quid, I've got a blindingly fast PC I was previously thinking of dumping. Then to make things sweeter I overclocked it to almost 4Ghz! And it took just 10 minutes to install.
3. If your Ubuntu PC won't come back from hibernation, it'll probably be due to a conflict with your NVidia card. Here's the solution.
4. If you can't log into your Ubuntu Samba-shared folder, make sure you're logging-in with the hostname specified, e.g. user@hostname !

But by far his favourite is 'Three Blind Mice', and he sings the line 'who CUT off their tails with a carving knife' with an impressive gusto!
